Abstract
A drawworks system for a mineral extraction system includes a drum mounted on a drum shaft and configured to support a cable. The system also includes a gearbox assembly having a gearbox housing, a gearbox supported by the gearbox housing and having a gearbox input shaft and a gearbox output shaft, wherein the gearbox input shaft is configured to be coupled to at least one motor and the gearbox output shaft is coupled to the drum shaft to drive rotation of the drum shaft and the drum, and a brake supported by the gearbox housing and coupled to the drum shaft to block rotation of the drum shaft and the drum, wherein the gearbox and the brake are positioned on one side of the drum along an axial axis of the drawworks system.
Claims16
A drawworks system for a mineral extraction system, comprising:
- a drum mounted on a drum shaft and configured to support a cable;
- a gearbox assembly, comprising:
- a gearbox housing;
- a gearbox supported within the gearbox housing and comprising a gearbox input shaft and a gearbox output shaft, wherein the gearbox input shaft is configured to be coupled to at least one motor and the gearbox output shaft is coupled to the drum shaft to drive rotation of the drum shaft and the drum;
- and
- a brake coupled to a wall of the gearbox housing via one or more fasteners and coupled to the drum shaft to block rotation of the drum shaft and the drum, wherein the drum shaft extends through the gearbox output shaft and into the brake, and wherein the gearbox and the brake are positioned on one side of the drum along an axial axis of the drawworks system.
A drawworks system for a mineral extraction system, comprising:
- a drum mounted on a drum shaft and configured to support a cable;
- a motor assembly configured to drive rotation of the drum shaft, comprising:
- a first motor and a first transmission configured to adjust a first power output of the first motor;
- and
- a second motor and a second transmission configured to adjust a second power output of the second motor;
- and
- a gearbox assembly comprising a gearbox supported within a gearbox housing and a brake disposed adjacent the gearbox, wherein the gearbox housing is coupled to a skid, and the brake is coupled to a wall of the gearbox housing via one or more fasteners and supported by the gearbox housing such that the brake is suspended above the skid.
